I have this Romin Mirror copy from Ryet and it is the best saddle I've ever had.
Weight was about 183gram so not the lightest.

I bought another one for my MTB because it was so good, especially compared to other lexon/ryet saddles. I've tried 4 of their saddles, but this is in a different league. Carbon looks way cleaner, and overall  3d print is really good.

Has different hard spots and soft spots, so I'm pretty sure some thought has gone into this saddle.

Other saddle I've tried from ryet are: Premium 3d (Saddle rails were out of alignment, so got a warranty, which was also out of alignment lol.), Ultimate 3d carbon, Aircode carbon

Let me know if you need any more if or pics of the saddle

Oh wow I was looking into the Romin copy as well along w/ the Power Mirror copy. Did the decrease length (compared to the actual Romin) change anything for you? AFAIK, the Romin is more of a curved saddle instead of a flat one like the Power so I was thinking the extra length would help in climbing

It looks like Chinese saddles are quickly improving their 3D printed mesh process. I'd be curious to give these a try.

Going from left to right, looks like a Romin Mirror (15mm shorter), Fizik Vento Argo, & a variation of Power Mirror.

The Romin Mirror has the most reviews from another listing while the other 2 do not have as much. I'm curious to try this as well but might just get the Velobuild's version of the SMP Dynamic to try
